SHOE-SHINING MACHINE.

To aAZZAwho/m. it may concern:

Be it known that I, AUGUST H. R. HELLEB, citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Shoe- Shining Machines, of which the following is a specification.

The present invention relates to improvements in shoe shining machines.

The primary object of the invention is the provision of a device of this character which will be simplein construction and operation and efficient for its purpose.

The invention consists essentially in the combination and arrangement of parts as hereinafter described involving a suitably operated machine, embodying a reciprothe traveling carriage.

eating carriage carrying brushes byv means of which polish furnished to the shoe may be brushed to shine the shoe. The machine is designed to operate on the shoes successively, and the brushing of the two shoes successively is accomplished. by a motor which actuates themachine during apredetermined number (sixteen) reciprocations of :The motive power is cut ofi'` at the end of the sixteenth reciprocai tion of the carriage by actuating mechanism,

and the brushes which are moved to polishi ing position to operate .on the shoe, are also removed fromoperative position by mechanism actuated at the end of the sixteenth reciprocation of the carriage. These and other features will be more 'clearly Aset forth in the accompanying specification and drawings. v

9 and 10 are fragmentary views ofA devices which assist in the actuation of one of the ratchet wheels. i"

The polishing machine is supported upon a frame or base 1 from which rise the rear supports 2, 2 for the motor 3. The motor actuates the two driving shafts 4, 5, which are Journaled in bearings 6 and extend 1ongitudinally from end to end ofthe frame. The shafts are revolved away from the center of the machine, e. shaft 5 revolves clockwise, and shaft 4 revolves anti-clocki Wise, and this motion is accomplished through the sprocket chain r7 which passes over thev sprocket 8 on the shaft 9,v of the motor, and over large sprockets 10- and 11 1 on shafts 4 and 5 respectively. An idle sprocket 12 is employed to ide the chain over the wheel 10 as shown c early in Fig. 2.

A reciprocable` carriage 13 is supported,

by the perforated ears orlugs 14, upon the shafts 4 and 5 and the carriage is free to slide on these shafts. The carriage is 4re ciprocated by a crank rod 15 which is pivotally connected to thepedestal 16 on the carriage frame and at. its other end is pivoted at 17 to the crank wheel 18 mountedon a studv shaft 19 journaled in the stationary frame of the machine. The crank wheelhas teeth 20 on its periphery meshing with the worm 21 on theshaft 5. From this description the transmission of the rotary motion of the shafts to the reciprocating motion of the carri-age will be evident. The carriage is intended to reciprocate a set of brushes in operative relationship .to a 'shoe placed on the .foot rest 22 which is stationary in the frame 1 of the machine. The carriage also carries a tank as 23, 24, one at each side and in operative relationship to the foot rest. These tanks contain liquid blacking and are provided with pipes as 25 equipped with a nozzle 26 from which the liquid blacking may be sprayed on the shoe as the carriage reciprocates, in determined manner and quantities. A stationary tank 27 is shown at the front of the machine whichhas the pipe 28 and nozzle 29 for spraying lthe heel comprise a pair of heel brushes 30, 30 that are relatively movable horizontally,a pair of toe brushes 31, 31', and a, single toe brush 32 that is movable vertically to adapt i itselfto the front of the toe of the shoe to be shined. The brushes are revolved from the two shafts 4 and 5, and as each brush of each pair is driven in similar manner, a description of one driving means will suffice for all four. A bevel gear 33 on the horizontal driving shaft engages a horizontally disposed bevel gear 34 on the Vertical shaft 35, and this shaft 35 bears a sprocket wheel 36 which is connected by chain 37 with the similar wheel 38 on the vertical shaft 39 upon which the brush is carried, and through Athese described connections the brush is revolved. The vertical shafts 35 and 39 transmit the power to the brushes, the shaft 39 being supported in a bracket 40 which is supported to oscillate on the shaft 35, the latter being revoluble in the carriage frame and acting as a pivot for the bracket as well. The brushes of each pair are urged toward each other byv suitable means, and the brushes of at least one pair (the heel pair) are forced apart after eight reciprocations of the carriage, in order to permit the withdrawal .of the shoe from the foot rest 22. This action is accomplished by mechanism clearly disclosed in Figs. 4 and 5, (see also Fig. l) wherein two plates 41 are illustrated on the brush bracket or holder 40. These plates are positioned to act as cams, and move in the path of a pair of bolts or tappets 42 located adjacent the stem 43 upon which the foot rest 22 is supported. This stem is fixed in the frame 1 of the machine, but is revoluble and carriesv a toothed disk orv wheel 44 provided with a cam lug 45 on itsvupper face. This lug is adapted to lift the bar 46 which carries the tappets 42, at certain predetermined intervals, e. at the end of eight reciprocations of the brush carriage, and this is accomplished by a pawl 44', 45 and 45t1 and hook 46 (Fig. 5) pivoted on the carriage which engages one of the sixteen teeth of the wheel 44 on each return movement of the carriage to the front. The eight successive engagements of the pawl 44 and hook 46 with the toothed disk 49 revolves the disk so that its lug 45 comesin contact with the lug 47 on the bar 46 and this contact of lugs lifts the bar 46.

The bar 46 is vertically slidable and on its under face `has a lug 47 in the path of movement of the lug 45, so that when the wheel 44 is revolved step by step the cam lug 45 finally engages the lug 47. The engagement of these lugs liftsthe bar 46 with its tappets` 42 against the tension of a fiat spring 48 which bears against the under face of a plate 49 which is perforated for the passage of the two tappets. The engagement of the parts 41 with the tappets `distends the brush holders or brackets as will be understood, and they are held distended until the two cams 45 and 47 pass'/v i out of contact which will be when the hook 46 engages the toothed wheel 44 on the next reciprocation of the carriage. It will be understood that this movement takes place at the end of each eight reciprocations of the carriage Ain order to permit the withdrawal of the shined shoe.

The brush 32 is revolved from the bevel gear 33 (dotted Fig. l) on shaft 4, which engages a similar wheel 51 on shaft 52 carrying the sprocket wheel 53, and this wheel is connected by chain 54 to a similar wheel on shaft 55. This countershaft 55 has a sprocket that is connected by chain 56 to a sprocket on shaft 57, and the shaft 57 has a sprocket which is connected by chain 58 to a similar sprocket on the brush shaft 59.

The brush shaft 59 is journaled in a pair of swinging brackets 60 which are connected by a tube or sleeve 61 over the shaft 57. The housing 60 (which is a part of the arm 60) has a stud or screw 60a secured thereon in path of movement of a lug 60b rotatable with the sleeve 61, see Figs. 1 and 6. The brackets 60 are provided with downwardly extending arms 62 which are pivoted at 63 to the car-l riage frame 13. -The brackets are adapted to oscillate on the sleeve 61 and shaft 57 to raise and lower the brush as the carriage reciprocates as followsr-A plunger rod 64 is pivoted at 65 to the arm 62 and the rod is supported to slide in the bracket 66 attached to the frame of the machine. A spring 67 is located on the plunger rod bef tween a fixed collar 68 and the bracket 66, and at the other side of the bracket a shock or buffer spring 69 is located between the bracket and a fixed collar 70 at the free end of the plunger. B v this arrangement of the plunger, and the bracket 66 as the plunger reci procates with the brush carriage the contact of the spring 67 with the bracket causes the oscllatable brush supporting frame to swing on its pivot 63 to eleva-te and depress the brush so that it will travel over the toe of the shoe from the lower point or tip of the sole up on top of the toe of the shoe to thoroughly brush the toe. When the brush carriage moves to the rear the rod 64 slides in its support 66 until the spring 67 contact with the same. Then the spring gradually compresses until it has reached the limit of its movement when the collar 68 takes up the pressure, and as bracket 66 is rigid with the base of the machine, the rod 64 presses against the portion 65 and the whole supporting mechanism of brush 59 rotates about lthe brush 52 can then reach farther back i brush to make a longer reach both vertically and horizontally. v

A suitable device (not shown) is provided to control the motor 3 by means of a connecting tappet rod 97 that is actuated from the bell crank lever 99 pivoted at 100 and in position to be moved by a projection 101 on the swinging brush frame 62. In this manner the bell crank is oscillated and the tappet rod 97 moved so that it will impart motion to the motor governor with each reciprocation of the carriage.

The operation of the machine is as follows: The heel brushes are held apart as described by means of the contacting cams. The patron places his shoe upon the foot rest and the motor is put in operation. The two driving shafts are revolved and with them all the brushes. The carriage is reciprocated and the liquid blacking spraying devices are-operated. The first reciprocation ofthe carriage permits the heel brushes to act on the shoe, and the eighth reciprocation cuts off the motor through the connection of the tappet rod 97. Afterlthe first shoe'is withdrawn the second shoe is now put in. place, the motor is again operated, and the machine performs until the carriage has reciprocated eight more times, When the motor is again cut off by the action of the tappet rod connection, and the machine is stopped.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. The combination Witha reciprocating carriage of a foot rest, a pair of brushes on the carriage, holders for the brushes, contact points on the holders, and means actuated by the reciprocating carriage to separate said-brushesby means of the contact the path'of the contact point to separate the brushes.

3. The combination with brushes as described of a. frame and a rack wheel supported thereon, a traveling carriage sup"- porting the brushes having a pawl adaptedl `i` to engage the wheel, and means upon the,

carriage projected by the predetermined rotation of said wheel into the pathy of movement of the brush holders and operating to separate the brushes. y

4. The combination with a supporting frame, a reciprocable carriage and brushes carried thereby, 4a rack Wheel in the frame and a cam lug thereon, means for extending the brushes, including a plate having a lug complementary to the lug of the rack wheel,

and a cam plate for each brush and meansA on the first mentioned plate adapted to contact with said cam plates operating to separate the brushes.

5. The combination of a reciprocable car` riage and a pair of separable brushes carried thereby, a supporting frame and a rack Wheel journaled therein, means on the carriage for turning the Wheel, a cam on the wheel, a perforated disk, a plate having a lug adapted to ride on said cam and a pair of bolts on the plate adapted to passy through said perforated disk into the pathvv of movement of the brush holders and operating to separate the brushes as described.

6. The combination with av pair-of separable brushes having contact members of a v supporting stem, a rack wheel on the stemv having a cam lug, and means for revolving the Wheel, a non-rotatable plate having a complementary lug adapted to ride on said lug on the Wheel, a perforated disk on the stem, a spring separating the plate and disk, and a pair of bolts carried by the plate adapted to pass through the perforated disk and engage said contract members to separate the'brushes.

7. The combination with a supporting frame bearing a perforated bracket, of a traveling carriage upon which is mounted a pivoted brush holder, a plunger rod pivoted to the holder and passed through said perforated bracket, and a cushioning spring between the holder pivot and the bracket., y v
